“Aperatif:
Let's get this out of the way first. The MSRP is a joke. $1299? Ha! Thankfully, on the secondhand market, prices have plummeted below $500, and I got mine on ebay (less warranty, less case, less the two other "sound filters"—I'm not sure which I got, but I think it's 'reference') for $312 including $5 shipping. AKG seems to have admitted this, putting them on permanent sale for...” --bosiemoncrieff

“After starting to review a few IEM's in the past week I decided to slip these babies back into my ears as a reference point for the other IEM's. After doing so for a few minutes I realized these really needed a proper review as they definitely keep up with a lot of gear that is more expensive.
